Yeah, it's guaranteed by virTypedParameterArrayValidate, any param
that not in the set VIR_NODE_MEMORY_SHARED_PAGES_TO_SCAN,
VIR_NODE_MEMORY_SHARED_SLEEP_MILLISECS, and
VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES will be detected,
and all of these 3 params contains "_".
Thanks the reviewing, I pushed it with the typos fixed.
